Ten\u00a0startups from Eindhoven have been honoured with\u00a0the Gerard and Anton Award 2016. The jury of the awards\u00a0thinks these ten have all it takes to follow\u00a0the footsteps of Gerard and Anton Philips who, 125 years ago, formed the first truly successful startup in the region. Every day we highlight one of those startups. Today: Microsure.<\/em><\/p>\n

The curation of\u00a0lymphedema: in the medical world it sounds like a desirable goal. But startup Microsure from Eindhoven is showing that this is possible, with the help of an assistant robot. E52 speaks with Ferry Schoenmakers, one of the developers of the machine.<\/p>\n

The jury:<\/strong><\/em><\/p>\n

“The TU\/e has enjoyed many successes in robotics. MicroSure is a spinoff delivering a real quality of life improving technology, based on the knowledge developed within the university.”<\/strong><\/em><\/p><\/blockquote>\n

\"Microsure3\"<\/a>With a huge smile on his face Schoenmakers shows the first prototype of MicroSure. This model has been tested at the University Hospital in Maastricht on ‘silicone tubes’, and later on animals as well. “Look, these vessels are attached to each other,” Schoenmakers says proudly, pointing to his hand on which he has laid the\u00a0extremely small pieces of silicon that are attached to each other. Schoenmakers himself has also learned to attach vessels with the robot, though it is by far not as smooth as when surgeon Ren\u00e9 van der Hulst operates the robot.<\/p>\n

The start?<\/strong><\/p>\n

Van der Hulst, the head of the Department of Reconstructive Surgery at the Academic Hospital Maastricht, and his\u00a0colleague Tom Mulken, asked the TU\/e to develop a robot that focuses on microsurgery. The old familiar Davinci (a widely used surgical robot) proved to be unsuitable for these operations. This device, which weighs over 600 kilos, was too big and bulky. A\u00a0compact and inexpensive robot that focuses on microsurgery had to be built. Schoenmakers:\u00a0“Van der Hulst feared for his job, since people after their fiftieth birthday have a less steady hand and microsurgery is therefore virtually impossible.”<\/p>\n

\"Microsure4\"<\/a>Now it’s time for Schoenmakers and his colleagues to bring the Microsure robot to market. “We have attended surgeries to experience\u00a0what the real problems are for the surgeons. It helps that I can stand the sight of blood”, Schoenmakers laughs. “We were amazed by how full the operating rooms already are. So our device cannot take up much space and the\u00a0surgeon may not trip over the cables. Also, the sterility is of great importance.”<\/p>\n

How does it work?<\/strong><\/p>\n

The device consists of two robotic arms and two “joysticks” that are controlled by the surgeon. The robotic arms which hold the instruments are to be placed under the microscope. Six axes enable\u00a0the movements of the hand, and a\u00a0pinching gesture with which the\u00a0tools can be operated. By using the joysticks, the surgeon operates the robot arms. Unwanted vibrations are filtered out and all movements are reduced. With a foot pedal, the speed can be slowed or the motion be put to a stop. “A surgeon can pause and perform actions step by step.”<\/p>\n

This can\u00a0actually be called a robot? “No,” he laughs. “It is nothing more than a dumb device that copies the movements of the surgeon. The word robot is actually wrong.”<\/p>\n

Main goal?<\/strong><\/p>\n

The main focus of the machine is\u00a0on the healing of lymphedema, an accumulation of lymph fluid in, for example, an arm. The causes may vary, for example, after surgery, radiation, infection, or even medication. Also, women with breast cancer frequently suffer from\u00a0lymphedema\u00a0after the removal of a lymph node. “Doctors normally don’t dare to do an operation like that. A lymph vessel is small and it is a delicate tissue. These\u00a0vessels have\u00a0a diameter of 0.3 to 0.8 millimeters. In comparison, a blood vessel is four times as large. Normally, tissue of\u00a0less than 1.5 millimeters can no longer be operated by hand. Also, for the repair of fine blood vessels and nerves, for example, within the neurology and vascular surgery, the Microsure robot can be used to allow for new treatments.”<\/p>\n

Of course there are opponents to the robot, says Schoenmakers. At conferences they face them. “Especially older surgeons think that a robot has no value because they have always worked with their hands in the past. But after we take\u00a0the conversation to lymphatic vessels, they start to see the advantages. At present there are only a handful of surgeons who can work without robot, with varying results.” Also, money plays a role. However, the robot is relatively inexpensive with a price between 200,000 and 300,000 euros. As a comparison: the Davinci cost 1.7 million with annual maintenance costs of 150,000 euros.<\/p>\n

MicroSure is in negotiation\u00a0with several interested hospitals. The Maastricht hospital\u00a0has already purchased the first system.<\/p>\n

A major challenge for the startup remains in the communication between technicians and\u00a0surgeons. Often there are\u00a0misunderstandings. Schoenmakers says this is the hardest part. “It’s still tough, but the cooperation is getting better. We are medically more educated, they have become more technical.”<\/p>\n

Future?<\/strong><\/p>\n

\"Microsure1\"<\/a><\/p>\n

In the distant future, the unit will deserve the name ‘robot’. At least that’s what Schoenmakers hopes. A robot with artificial intelligence, which can prevent\u00a0stupid mistakes by a surgeon or even take over parts of the surgery, Schoenmakers\u00a0believes it is possible. Occasionally, the team has been experimenting with it. “I estimate that this is possible in twenty years.”<\/p>\n

At this time, the purpose is to get all the needed certification, and sell it worldwide. “Microsurgery is booming, I can see this at the conferences we attend. There is no direct competitor, but we do feel the pressure to hurry up.” In 2017, the first lymphedema surgery is planned. “If we succeed, we have a new field of surgical expertise.”<\/p>\n
